The idea of this rocket was to get through Mach 1 with on-board videotransmittion. It was very tigh getting in all of the equipment and batteries required. The transmitting helical antenna was made quite short to widen the beam and hopefully pick up most of the flight. The recieving antenna was made longer (about 1M).
Wrasp suggested that it would do Mach 1 with a J570W. I have no way of telling if it did, but the on recorded video is quite somthing. The ground rushes away VERY fast. The altitude was predicted to be over 9000 feet. We launched the rocket twice at UKRA 2002. Both flights landed back within 100 feet of the pad. NO dual deployment was used. We calcuated wind speed and angle and direction of the launch rod using some simple calcs. And it worked.
Fins are all aluminium and are bolt on (M3) with countersunk heads. A tee section runs through the body wall. The body is close to minimum diameter.
